The radiator may be connected to the hot water circuit, this was pretty common a few years ago and is still requested now to keep a warm bathroom and towels during summer months when main heating isn't being used

Further to peters post I am quite intrigued as to what fuel he has in mind to replace oil in areas not supplied by mains gas which is cheaper, ground source, air source and solar heating are options with very limited capacity, certainly not able to cope with anything on this scale.

provided one pipe is from flow and the other is from return the probable cause is a stuck TRV or defective sensor head

I take it this is a combi boiler, probably the diverter valve is not operating correctly get an engineer to check it out. Unless you can post model I can't offer any further detailed help

Combis are entirely suitable for family homes where there may be a large hot water demand,and Vaillants are a very good make of bolier, possibly the best although Baxis are also very good. Alphas are very good but not quite up to the same standard in my opinion

Has the system been cleaned? Flush the system before adding inhibitor. Is the system fed from a tank or a sealed system?

Do not attempt to fix this fault yourself, the carbon monoxide associated with boiler flues is lethal and may endanger yourself and you family. Get a CORGI registered engineer to check this out. I believe you have identified the problem but be safe before you operate the appliance

When the valve is open the microswitches inside the motor housing make a circuit bringing on the pump. Replacement valve heads cost sround £40 and require some basic wiring to r...

Be careful here, Eaga ran the scheme in Scotland until they were bascially sacked and the contract handed to Scottish Gas.
